Theresa Magdalena Margarita Ann Russo (née Larkin) is the mother of Alex, Justin, and Max Russo. She runs the Waverly Sub Station with her husband, Jerry Russo. As a mortal, she possesses no powers, but encourages her children's discovery of things such as school and their Latino heritage (Alex and her brothers are half Mexican from Theresa's side of the family). She does not like magic, and she can not stand when she finds "magic running amuck in the house."
